A method and apparatus for using liquid nitrogen to render crises safe, as in circumstances of hostage crises, entering Methamphetamine labs, purging the accumulating toxic or flammable gases, ending the dispersal of substances from aerosols and capturing the material dispersed by condensing it and sealing it in containers for disposal, picking up spills by solidifying them or gelling the material and containing it for disposal—this includes Mercury spills, sealing and repairing broken pipes and dikes and dams, enabling a combustion engine to quit running, strengthening levee structures by freezing the core for the length of the levee or sandbag structure when severe crises occur, rapid cooling lava flows to structure the solid lava formation to something useful in that location, purging the coalmine fire environment of Oxygen to quell the long-term blaze while cooling subterranean structure to below freezing causing water crystals to loosen structure, treating industrial stack gas to capture acidics and use soot, water and Carbon dioxide components, air drop Liquid Nitrogen, freeze ordnance buried underground freeing it from target structure, and countering aircraft collision situations in tall buildings. These methods can apply in wider circumstances and are enabled by either aperture dispersal of Liquid Nitrogen or pre-pipe evaporation for rapid cooling as the Nitrogen gas emerges and is released safely into the atmosphere.
A method of using liquid nitrogen to control crises comprising the steps of:
A method of capturing the gaseous Nitrogen after it evaporates such that the coldness and inertness can affect the target crisis most effectively by encircling the crisis with a ring with a sealing bottom that conforms to the surface thus keeping the coldest Nitrogen gas in contact with the item to be cooled to solidify or gel contents or other function, or having a hammock-like sling under a pipe structure needing its contents frozen with one or more volume regions to hold the coldest Nitrogen gas.
A method of dispersing Liquid Nitrogen into an entrance to a pipe system whereby the cryogenically cold gas enters the pipe system causing freezing of the pipe environment and, at the same time, allowing safe exit of the expanding gaseous Nitrogen.
A method of scrubbing stack gas from factory or coal burning generator chimneys comprising the steps of:
A method of cooling ordnance underground using a hollow drill which carries Liquid Nitrogen to the level Of the ordnance cooling it to an inert state, disentangle ordnance connected to underground structure with a water cutter and pull the cryogenically cold ordnance to the ground level in the path of the hollow drill.
A method for safely using any of the Liquid Nitrogen techniques of having Oxygen masks available to protect persons from breathing the Nitrogen cloud pure Nitrogen, and when the Nitrogen cloud is applied to protect them from toxins, flammable gases that might explode and such other situations where these methods are used including fires where
